by triangle angle addition law
a + b + c = 180
3x +1 + 2x-1 +40 = 180
5x +40 = 180
5x = 180 - 40 = 140
x = 140/5 = 28
so
b = 2x -1 = 2×28-1= 56-1 = 55

Answer:
Given that tan x = 5/12, what is the value of sin x + cos x?
draw a triangle with opposite leg=3 and hypotenuse=5
tan p = opposite/adjacent = 3/4
similarly, in a 5-12-13 right triangle
sin x + cos x = 5/13 + 12/13
